How does Wi-Fi Work
Wi-Fi is a wireless technology used in home networks and to connect mobile phones, computers and many such electronic devices over a wireless network. It is the 802.11 IEEE standard. How does Wi-Fi work? Here's how.
The wireless adapter of a computer translates data into radio signals and transmits the signals over an antenna. The transmitting antenna is generally connected to a DSL or a LAN-based Internet connection. The wireless router in the network receives the signals and decodes them. The router uses an Ethernet connection to transmit the information over the Internet. The places or spots, which offer Wi-fi access to the Internet, are known as Wi-Fi hotspots.
The Wi-Fi signals have a range of about 120 feet indoors and 300 feet outdoors. With an increase in the distance between the user and the signal, the connection speed decreases. Wi-Fi connections allow you to get rid of the clutter of wires. WI-fi networks are easy to set up. Wi-Fi makes it possible for LANs to be deployed without cabling. This reduces the costs incurred in the network setup and expansion.
The use of Wi-Fi technology for Internet access is on the rise. Companies and households have begun opting for wireless Internet access. Read how wireless Internet works if you plan to switch to wireless networking for web access.
